Check Digit Verification of cas no
The CAS Registry Mumber 31596-87-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,1,5,9 and 6 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 31596-87:
(7*3)+(6*1)+(5*5)+(4*9)+(3*6)+(2*8)+(1*7)=129
129 % 10 = 9
So 31596-87-9 is a valid CAS Registry Number.

DECOMPOSITION OF ARILAZIDES AND P-TOSYLAZIDE BY THF/n-BUTYLLITHIUM. A NEW SOURCE OF DIAZOMETHANE
Babudri, F.,Di Nunno, L.,Florio, S.,Valzano, S.
, p. 1731 - 1736 (2007/10/02)
Variously substituted arylazides, as well as p-tosylazide, when allowed to react at room temperature with THF previously treated with n-butyllithium, undergo a rapid decomposition affording the corresponding amines and formamides, together with diazomethane.This diazo transfer (with deformylation) reaction is thought to involve the enolate of the acetaldehyde generated by the known cycloreversion of THF in the presence on n-butyllithium.
