Check Digit Verification of cas no

The CAS Registry Mumber 887706-98-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,8,7,7,0 and 6 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 887706-98:
(8*8)+(7*8)+(6*7)+(5*7)+(4*0)+(3*6)+(2*9)+(1*8)=241
241 % 10 = 1
So 887706-98-1 is a valid CAS Registry Number.

METHODS FOR PURIFYING TRANS-(-)-Δ9-TETRAHYDROCANNABINOL AND TRANS-(+)-Δ9-TETRAHYDROCANNABINOL

-

Page/Page column 43, (2008/06/13)

Methods for making trans-(-)-Δ9-tetrahydrocannabinoI and trans-(+)-Δ9-tetrahydrocannabinol are disclosed herein. In one embodiment, a trans-(-)-Δ9-tetrahydrocannabinoI composition is prepared by allowing a composition comprising (±)-Δ9-tetrahydrocannabinol to separate on a chiral stationary phase to provide a trans-(-)-Δ9-tetrahydrocannabinoI composition comprising at least about 99% by weight of trans-(-)-Δ9-tetrahydrocannabinol based on the total amount of trans-(-)-Δ9-tetrahydrocannabinol and trans-(+)-Δ9-tetrahydrocannabinol. The invention also relates to methods for treating or preventing a condition such as pain comprising administering to a patient in need thereof an effective amount of a trans-(-)-Δ9-tetrahydrocannabinoI having a purity of at least about 98% based on the total weight of cannabinoids.
