Check Digit Verification of cas no

The CAS Registry Mumber 129199-20-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,1,9 and 9 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 129199-20:
(8*1)+(7*2)+(6*9)+(5*1)+(4*9)+(3*9)+(2*2)+(1*0)=148
148 % 10 = 8
So 129199-20-8 is a valid CAS Registry Number.

PROLONGED TREATMENT OF ACETYLMETHYL URSOLIC ACID WITH H2O2/ACETIC ACID - A FACILE ONE-POT SYNTHESIS OF 15α-HYDROXY ANALOGUE

Siddiqui, Salimuzzaman,Siddiqui, Bina Shaheen,Adil, Qayyum,Begum, Sabira

, p. 3569 - 3580 (2007/10/02)

With a view to obtain new compounds bearing potential applications in the biogenetic type synthesis of natural products, acetylmethyl ursolic acid (1) was subjected to prolonged treatment with H2O2/AcOH on boiling water bath.Several such products (2, 3, 5 and 7) have thus been obtained.A new one-pot partial synthesis of 15α-hydroxy Δ12-analogues of pentacyclic triterpenes of amyrin series has been achieved. 13C-NMR spectral data of the major product are also described.
