Check Digit Verification of cas no

The CAS Registry Mumber 132776-59-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,2,7,7 and 6 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 132776-59:
(8*1)+(7*3)+(6*2)+(5*7)+(4*7)+(3*6)+(2*5)+(1*9)=141
141 % 10 = 1
So 132776-59-1 is a valid CAS Registry Number.

, p. 477 - 480 (2007/10/02)

When peracetylated iridoid glucosides are submitted to hydroxymercuration and reduction with zinc the glucoside bond is cleaved exclusively.The aglycones can be regio- and stereoselectively transformed into specionin analogs.An example is the preparation
